Method of making a multi-layered pressure hose utilizing internal fluid pressure

摘要

A method of manufacture of pressure hose is described. An uncured tubular structure including one or more sub-units each having a radially inner tubular layer of uncured elastomer and an outer tubular layer of filamentary reinforcing elements is subjected to fluid pressure in its bore. The fluid pressure forces uncured elastomer material into the interstices of the filamentary layer of each sub-unit and consolidates the uncured structure. A cover layer of elastomer material is thereafter applied and the covered structure is cured into an integral hose.
